Dominant R wave in aVR
Results:
VT vs. SVT with Aberrancy
Key Points Basic Distinction: SVTs typically have narrow QRS complexes (<120 ms) but may present with wide complexes if aberrantly conducted (e.g., with existing bundle branch block). Clinical Importance: Differentiating…
Tall R wave in aVR DDx
Key Points Normal expectation: In aVR, the QRS is usually negative (deep S wave). A dominant or tall R wave (R > S) is abnormal and should prompt investigation. Mechanism:…
